A Visual Language for Modeling Multiple Perspectives of Business Process Compliance Rules (Extended Abstract)

A fundamental challenge for enterprises is to ensure compliance of their business processes
with imposed compliance rules stemming from various sources, e.g., corporate guidelines, best
practices, standards, and laws. In general, a compliance rule may refer to multiple process perspectives
including control flow, time, data, resources, and interactions with business partners. On one
hand, compliance rules should be comprehensible for domain experts who must define, verify and
apply them. On the other, these rules should have a precise semantics to avoid ambiguities and enable
their automated processing. Providing a visual language is advantageous in this context as it allows
hiding formal details and offering an intuitive way of modeling the compliance rules. However, existing
visual languages for compliance rule modeling have focused on the control flow perspective so
far, but lack proper support for the other process perspectives. To remedy this drawback, we introduce
the extended Compliance Rule Graph language, which enables the visual modeling of compliance
rules with the support of multiple perspectives. Overall, this language will foster the modeling and
verification of compliance rules in practice.
